description = """ISO 4762 (DIN 912) hexagon socket head cap screw. Envelope geometry for assemblies: head (dk max, k max), \
hexagon socket (s, t min) and a plain shank at the nominal thread diameter; the thread itself is not modelled.

The head's bearing face is on the XY plane at the origin and the shank points along -Z; `length` is the nominal \
length under the head. Dimensions from ISO 4762:2004 Table 1 (see the README)."""
